JOURNAL AND BOX FOR RAILROAD-CARS.

Specification of Letters Patent No. 28,129, dated May 1, 1860.

T o all whom t 'may concern:

Be it known that I, I-IUMPHREY JACKMAN, of Elizabethport, in the Stateof New Jersey, have invented a new and useful Improvenient in Journalsand Boxes for Railroad-Cars and other Purposes; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing, making part of thisspecification, which represents a vertical section taken in the plane ofthe axis of the journal.

The object of my said invention is to prevent the escape of oil fromrailroad and other like journal boxes in general, although speciallyapplied to a railroad box described in Letters Patent granted to Leon J.Pomme de Mirimonde, on the 23rd day of August, 1856.

Various attempts have been made to prevent the escape of oil from theboxes of railroad cars where the axle enters the box, but all suchattempts have, so far as I am informed, failed to produce the requiredresult. In the railroad box described in the before recited LettersPatent there are friction rollers in the upper part of the box restingon the journal of the axle, and for the purpose of keeping the journalsof the said rollers well oiled at all times the journal of the axle isprovided with project-ing shoulders at each end armed with bristles orother equivalent means which, in the revolution, dip into the oilcontained in the lower part of the box, and carry it up and apply it tothe journals of the rollers. This it is found in practice has a strongtendency to waste the oil at the opening surrounding the axle, howeverthis may be packed.

The escape of the oil is effectually prevent-ed by my invention whichconsists in combining with the journal box and ournal and the frictionrollers above a cone upon the axle, and interposed between the journaland the face of the box through which the axle passes, the base orlarger end of the said cone being' toward the journal, by means of whichcombination all the oil which gets onto the axle in consequence ofoiling the journals of the rolls above, and which other wise wouldtravel along the surface of the axle and finally escape from the box, iscaused by Centrifugal action to travel up toward the base of the cone,and carries the l' oilwhere it is required to supply the journals of thefriction rollers.

In the accompanying drawing (a) represents the box made in two partsfirmly bolt ed together, and the axle with the journal or bearing part(c) between projecting shoulders or co lars (d, d), which collars areprovided with bristles (e) or other projections which dip in the oilconta-ined in the lower part of the box. There are two -rollers (f, f)(one only shown in the drawing) which rest on the journal (c) of theaxle, and the upper part of the box is provided with small ournal boxes(g, g) which rest on the journals (7i, 7L) of these rollers leaving thelower part of their peripheries exposed to receive oil from the bristlesor equivalents (e) so that by the rotation of the axle the oil containedin the lower part of the box is constantly carried up and supplied tothe journals of the rollers to keep them oiled.

The axle (b) passes through a circular hole in the inner face (i) of thebox which is provided in the usual manner, with a leather packing (j)fitted to a groove (la) in the axle to prevent dirt from entering thebox, and also to prevent oil from escaping, but oil travels so readilyon the surface of metals that the use of such leather packing is not aneffectual means to prevent the escape of oil.

Between the leather packing and the collar (d) and at that end of thejournal the axle is made of a conical form as at (l) the said collar(CZ) forming the base of the cone, so that the oil which is thrown ontothe surface of this conical part, and which if not of that form, wouldfind its way out of the box, is caused by the rotation of the axle, andby centrifugal action, to travel toward the base of the cone, and henceaway from the packing, and is carried back to that part of the box fromwhich the bristles or other projections on the axle can take it to oilthe journals of the rollers. In this way the waste is eifectuallyprevented.

I do not wish to be understood as limiting myself to the specialconstruct-ion of box herein specified, as the box makes no part of myinvention.

That I claim as my invention, and desire to secure by Letters Patent,is-

The said cone on the axle in combination with the box provided withfriction rollersl the operation of lubricating the journals of thejournals of Which are supplied with oil the rollers, and carry it backinto the box, by projections on the axle, which by the as specied.
